Composite arched in-site casting floor frame constructing structure

Abstract

The invention relates to a building structure, in particular to the building structure of a combined arched cast-in-place floor slab frame, which comprises a main beam and a floor slab, wherein the joint part of the main beam and the floor slab is provided with an arched beam support, a section of the main beam positioned in the arched beam support forms a concealed beam, and a reinforcing steel bar of the main beam has a reinforcing steel bar net post shaped structure, wherein the reinforcing steel bar net post of the concealed beam is provided with a beam reinforcement stirrup. The reinforcing steel bar of the arched beam support is arranged in a cone shape, one end of which is integrally connected with the beam reinforcement stirrup on the reinforcing steel bar of the concealed beam into a whole, while the other end of which parallelly extends into the reinforcing steel bar of the floor slab and is connected with the reinforcing steel bar of the floor slab into a whole. The reinforcing steel bar arched beam support is arranged in the cone shape so that the arched beam support is not only firm and durable, but also saves a large number of the main beams and secondary beams, saves the materials, wherein the steel usage is saved by 60 percent, the amount of concrete is saved about 30 percent, and the labor is saved about 40 percent.

Description

Technical field: [0001] The invention relates to a building structure, in particular to a combined arched cast-in-place floor slab frame building structure. Background technique: [0002] At present, the building structure adopts reinforced concrete frame structure, masonry structure, slab-column structure, steel structure, etc. Reinforced concrete columns are poured on the foundation, and a large number of primary and secondary beams, well beams, floor surfaces, and slab surfaces are poured between the columns. It is transmitted to the secondary beam, then to the main beam, from the main beam to the frame column, and from the column to the foundation. The force transmission route is long, and a large number of concrete beams and columns must be required. The amount of steel and concrete is relatively large, which not only wastes materials , and the resultant structure is self-heavy, the foundation and the foundation are wasted, the amount of steel is large, the cost is high...
